Twist-tuned exchange and hysteresis in a bilayer van der Waals magnet.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Moiré superlattices in twisted bilayers enable strong reconstruction of electronic band structures, giving rise to correlated phases with high tunability. Extending this concept to van der Waals magnets, we show that twisting induces spatially varying interlayer exchange interactions that can stabilize complex magnetic responses. Here, we demonstrate robust magnetic hysteresis in bilayer CrSBr upon a twist of ~ 3°, observed as a hysteretic evolution of exciton energies that directly track the underlying magnetic configuration in field-dependent photoluminescence measurements. An analytic two-sublattice model captures this behaviour, attributing it to a twist-induced reduction of interlayer exchange that stabilizes both parallel and antiparallel spin states over a broad field range. Spatially resolved measurements reveal local variations in hysteresis loops, consistent with position-dependent modulation of magnetic parameters. In certain regions, coherent averaging over the moiré unit cell yields an effective monodomain-like response. Our results establish twist engineering as a route to programmable magnetism in two-dimensional antiferromagnets.
